IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 175,620, dated April 4,1876; application filed October 11, 1875.

To all whom it may concern:

Be it known that I, ABNER N. NEWTON, of

v Richmond, county of Wayne and State of Indiana, have invented certainImprovements in Corn-Planters, of which the following is a specificationThis invention relates to corn planters or drills, having variousdevices which are arranged to be readily adapted for a single or doublerow dropper, at pleasure, as will be more fully hereinafter describedand set forth in the claims.

Figurel is a perspective view with the left wheel removed. Fig. 2 is aplan or top view of the hopper, showing the stationary agitators toinsure perfect filling of the seed-cells. Fig. 3 is a bottom view of thehopper with the dropper-plate attached. Fig. 4 is a verti- Fig. 5 is asection showing the manner of attaching the change-wheel to the hub ofthe drive or ground wheel.

Ais the axle; B B, the thills; G, the groundwheel; D, the hopper; E, thetoothed dropper-plate; F, the change-wheel attached to the hub of theground-wheel. G is a lever, by which the dropper-plate E is raised orlowered into the different sets of teeth in the change-wheel. H is atoothed rack for the purpose of holding the lever G in any desiredposition. I is the self-adjusting grain-spout, having the arms J Jattached, said arms carrying the coverers K and roller L, by which thespout is kept in place and made selfadjusting, the coverers also beingadjusta ble by means of the roller L and set-screws a in the shank ofthe coverers to raise and lower them, according to the depth it is desired to cover. When adjusted to cover the required depth the rollerholds them to that depth, thereby insuring even covering. The bar M isattached to the grain-spout, and

- pivoted at its forward end to the thill, consequently admits ofself-adjustment while the machine is in operation.

The section, Fig. 5, shows the manner of attaching the changewheel F tothe hub of the ground or drive wheel, which may be done by casting theboxing of the hub to the change- Wheel; or theboxing may be omitted fromthe circular bar or ring 0 attached to it, the bar 0 being of less widththan the seed-cells P in the dropper-plate E, for the purpose of makingchad-openings on either side of the circular bar- This bar 0 also hasthe spout R at taehed, Which spout passes down inside of the upper endof the grain-spout I, the spout I sliding up and down upon it as itadjusts itself to the work. There are lugs V attached to the upper endof the hopper. The lugs V and V slide upon the vertical rods T by theirholes S sliding over the rods, the center rod being the pivot upon whichthe toothed dropperwheel turns. A, Figs. 2 and 4, is a conical disk,placed in the center of the hopper for the purpose of forming the recess13, into which the grain presses by its own weight, but is keptsufficiently stirred to always fill the seedcells by means of thependent agitators U attached to the cross-bars U. These pendentagitators, in conjunction with the cross-bars U, keep back the grainfrom crowding the exit-0rifice of the hopper or dropper-plate, at thesame time keeping the grain sufficiently agitated to insure the fillingof the seed-cells. D, Fig. 4, represents a weighted pivoted cut 05, ofwhich any required number may be used. They are placed side by side, asshown at D, Fig. 2, in the recess crossed by the line X X. Theseweighted pivoted cut-offs have adjusting-holes E, Fig. at, for thepurpose of giving greater or less pressure to the cutoff, as occasionmay require. The upper end of these weighted cut-offs leans forward inorder that their lower ends may press upon the dropper-plate by meansol'jthe weight of the upper end.

The hopper D, dropper-plate E, cross-bar N, and circular bar 0 actconjointly, and move together in making the different changes, and aremoved up or down by means of the lever G applied to the under surface ofthe bar N at its center. The weighted idler'G rests upon the uppersurface of the dropper-plate in line with the seed-cells P, and is madesomewhat larger than the cells, but will drop sufficiently into thecells to force the grain out. This idler is attached to the lower end ofthe upright weight F.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. The combination of the toothed dropperwheel E, hopper D, pivot-rod T,and vertical change-wheel F, for the purpose substantially as described.

2. The conical disk A, having the stationary agitators U and pendentagitators O attached, in combination with the hopper D, substantially asdescribed.

3'. The circular bar 0, as shown and described, in combination with thedropper- Wheel having the seed-cells P, for the purpose specified.

4. The combination of the bar N and circular bar 0 attached to thehopper, and having the horizontal toothed dropper-plate E workingbetween the said bars, the whole sliding upon the rods T, substantiallyas and for the described.
